DIESEL ENGINES AND SELECTIVE CATALYTIC REDUCTION: WHAT YOU NEED TO KNOW

We explain what emissions legislation means for our cars, our drivers and the environment.

WHAT IS EMISSIONS LEGISLATION?

Emissions legislation is aimed at making cars more environmentally friendly by limiting their exhaust emissions.

Jaguar offers engines suitable for local conditions around the world. For diesel, we offer the system known as Selective Catalytic Reduction (SCR). It helps us achieve the lowest possible emission levels while maintaining good behavior in other areas, such as refinement and fuel consumption.

To assist tailpipe emission control, the system uses an additive known as Diesel Exhaust Fluid (DEF).

WHAT IS SELECTIVE CATALYTIC REDUCTION (SCR) TECHNOLOGY?

Selective Catalytic Reduction (SCR) technology is fitted to all Jaguar diesel vehicles from the 2016 model year. It enables Jaguar to meet local emissions legislation by reducing the levels of nitrogen oxide (NOx) emitted from the exhaust system by up to 90%. In addition to a new generation of catalytic converter, SCR Technology requires the use of Diesel Exhaust Fluid (DEF).

WHAT IS DIESEL EXHAUST FLUID (DEF)?

DEF, also known as AdBlue®, AUS 32 and ARLA 32, is a non-toxic, colorless, odorless and non-flammable fluid. Stored in a dedicated tank in your car, DEF is injected into the exhaust system to clean exhaust gases. It breaks down nitrogen oxide (NO(x) emissions into harmless water vapor and nitrogen gas.

MAINTAINING DEF

It’s important that your Jaguar vehicle’s supply of DEF is maintained, as government regulations prohibit you starting the engine without it. Your car’s message center will give you advance warning when your DEF level is low and will alert you in plenty of time to book a refill. Your local Jaguar Retailer will also refill the tank as part of your scheduled maintenance. Please refer to your Owner's Handbook for more information.

NOTE: When the DEF level becomes low, a notification message displays in the message center. Refill the DEF tank at the earliest opportunity. A Jaguar Retailer can be contacted to arrange a full DEF refill. If required, DEF can be refilled using non-drip refill bottles available from a Jaguar Retailer. An average consumption of DEF is 2,8L (6 pints) per 1000 miles. However, consumption can vary greatly depending on your driving style, the weather and road conditions.
